22 Claims. (Cl. 139---3 Zl3) This invention relates to weft replenishing looms and more particularly to thread cutting temples, and it is the general object of the invention to provide the temples with a movable cutter blade always under positive control and with thread control means to prevent or permit cutting of a thread depending upon whether the thread is that of a stored shuttle or one involved in a weft replenishing operation.

Certain looms that have gone into general use employ a shuttle box at the magazine side of the loom, having at least two shuttle cells, which rise and fall during loom operation to receive or eject a shuttle. When weaving certain fabrics, it is necessary, because of pattern requirements, to store a shuttle in one of the cells by moving the cell into inactive position for a number of picks while the weft or thread of an active shuttle is being laid in the shed after which the stored shuttle again becomes active. During inactivation of the stored shuttle, the weft or thread associated therewith will extend from the selvage to the stored shuttle and during continued weaving will be moved forwardly into range of the temple cutter blades whereby cutting of the weft will occur and when next the stored shuttle becomes active no weft will be laid, and the loom will be stopped by the usual weft stop motion. ,It is therefore an important object of the invention to provide means to prevent cutting of the thread of a shuttle when the latteris to be stored at the magazine end of the loom for a number of successive picks.

Another object of the invention is to provide a thread guarding and guiding means effective not only to guard against cutting of the thread of an inactive shuttle, but also effective to guide the thread of an outgoing and incoming bobbin into thread cutting position incident and subsequent to aweft replenishing operation respectively.

Still another object of the invention is to make the thread guarding and guiding means L-shaped having a rearwardly facing notch between the vertical and horizontal parts thereof, and to mount said means between the selvage of the fabric being woven and a movable thread cutter blade, such that the horizontal part ex tends toward and supports the selvage to guide the threads extending therefrom into said notch, and the vertical part coacts with a stationarycutter blade to frictionally hold the movable blade and prevent movement thereof until acted upon by blade actuating means interposed between one end of the movable blade and the lay.

A further object of the invention is to prevent sluggish operation of the movable blade by eliminating the springs or weights commonly used in connection with the movable blade and the force transmitting parts that move the blade.

A further object of the invention is to actuate the movable blade positively for a cutting operation by said blade actuating means while the lay is moving rearward- 2,868,235 Patented Jan. 13, 1959 ly and to return said blade positively by said means to open or noncutting position while the lay is moving forwardly.

A further object of the invention is to provide the said blade actuating means with a force transmitting member effective to actuate the movable blade positively and capable of being freely moved in a forward direction to prevent breakage of the temple, said means, or said blade when the temple is moved forwardly in the usual manner because of a misplaced shuttle.

A still further object of the invention is to provide the blade actuating means with a connection whereby the time of the cutting operation may be varied.

Other objects of the invention will appear as the description proceeds, and in order that the invention may be clearly understood reference is made to the accompanying drawings which illustrate by way of example three embodiments of the invention and in which:

fig. 14 is a diagrammatic plan view showing the new or incoming thread of a transferred bobbin in position to be cut.

Referring particularly to Figs. 1, 2 and 7, right and left-hand loomsides l and 2 respectively support therebetween a breastbeam 3 over which the cloth C passes to the usual cloth roll, not shown. The loomside .also support a rocker shaft 5 on which is mounted a pair of reciprocating layswords 5 (only one of which is shown) having fixed thereto. the usual lay L and reed R for back and forth movement during loom operation.

The lay carries a lay end a which supports and guides a gang G of shuttle boxes having upper and lower cells 7 and 8 respectively to receive into or have ejected therefrom shuttles Si and 32 as the case may be. The gang G is lifted and lowered in well-known manner by a box lifter rod 9 under controlof afiexible connector 11 operatively connected to rod 9 as at 12 from which the flexible connector extends over a pulley l3 and thence to the head mechanism (not shown) on the opposite end of the loom. During loom operation either of the cells 7 or 3 will be moved by rod 9 to so-called running position to receive or eject a shuttle and when a shuttle is to be stored fora number of successive picks becauseof pattern requirements the shuttle will be picked into cell 7 and the gangG will be moved to the dotted line position, Fig. 1, whereby cell 3 will be in running position to receive or pick a shuttle.

A weft detector. generally indicated at D, Fig. l, is mounted on a slide 14 and is guided for vertical movement 'by a stationaryarm 15 depending from a reserve bobbin magazine M. The upper end of a rod is c-W. nected to slide M and the lower end is connected to an arm 17 fast on rod 9. The weft detector D is aligned with cell '7 and rises and falls with gang G, but does not have a back and forth motion as does the gan, Dated tion of Weft exhaustion and subsequent trap r of :1 bobbin from the magazine into an empty shuttie can occur only when the layis at front center position, that is, detection will occur when the gang G is ap roaching the dotted line position shown in Fig. l, and transfer will occur on the front center following detection with the gang in said position. 1

The matter thus far described is of common construction and operates in the usual manner.

The invention as set forth herein contemplates the use of a temple generally indicated at T and, except as noted hereinafter, is of usual construction having a pair of caps 18, temple rolls 19, only one of which is shown, see Fig. 4, ahead 21 a shank 22 and a casing 23. The temple is mounted for lateral and back and forth adjustment on a plate '24 fast on the breastbeam 3. Shank 22 supports rear cap 18 and head 21 and extends into the casing 23 wherein the usual spring (not shown) urges the shank .rearwardly. When a shuttle is trapped or misplaced (see dotted position of shuttle in Fig. 2) between the rear R and the head 21, continued forward motion of the lay will cause the shuttle to move the shank 22. and parts supported thereby forwardly to prevent damage or breakage to either the shuttle, the temple, or both. Under these conditions the loom will be automatically stopped by well-known protector mechanism in the usual manner after which the shuttle will be manually placed in the proper shuttle box. Removal of the shuttle from between the reed and the head will cause the then compressed spring in the casing to expand to move the shank rearwardly until the rear cap 18 and head 21 are back in their normal rear position, whereby the loom will again be ready for operation.

In carrying the preferred form of the invention into effect, the head 21 is provided with a vertical recess 25 extending longitudinally through the head and providing an opening at the bottom thereof as seen for instance in Fig. 7. Recess 25 has narrow portions 25a and 26, Fig. 4, to receive the upper ends of a stationary cutter blade 27 and an L-shaped member 28 respectively. Blade 27 i and member 28 are mounted within the recess or slot 25 and are held fast to the head by a screw 29 threaded into the head 21. Member 28 has a vertical and horizontal leg 31 and 332 respectively and a rearwardly-facing continual notch 33 between the legs to receive the thread of a stored shuttle and the threads of an incoming and outgoing bobbin respectively. Leg 32 is at right angles to leg 31 and extends toward the cloth C and partially under the latter to support the selvage and to guide the threads extending therefrom into notch 33. Member 28 may be considered thread control means or more particularly thread guarding and guiding ineans.

As viewed in Fig. 4, stationary cutter blade 27 and L-shaped member 28 are spaced laterally from each other and receive'frictionally therebetween the rear end 34% of a movable cutter blade generally indicated at 35 pivoted at -36-on the head 21. A A cutting edge 37 on movable blade 35 cooperates-with a cutting edge 38 on blade 27, see Fig. 6, to have a cutting operation while the lay L moves rearwardly.

Referring particularly to Figs. 7, 8 and 9, the lay L supports a rod 39 journalled in brackets 41 fixed to the lay L in any approved manner. Rod 39 moves in an arcuate path generally indicated by the numeral concentric with the axis of rocker shaft 4 and is operatively connected to a lever generally indicated at 42 having upper and lower arms "43 and 44 respectively, spaced from each other by collars 45 and held rigid with respect to each other by bolts 46 passing through the arms and collars and fastened thereto by nuts 47. Arm 43 has an arcuate portion (-58 which partially surrounds a tubular shaft 49, and arm 44 has a straight'end portionSlt which contacts shaft 49, both of said portions forming a hearing for pivotal movement on shaft 49. Arm'44 has a rearwardly extending straight part 52, a curved part 53, and a forwardly extending straight part 54, said parts forming an open end straight slot to receive the rod 39.

Arms 43 and 44 have clamped thereto a rod 56 the upper end of which is pivotally connected as at 57 to the lower end of a link or force transmitting member 58 having pivotal connection at its upper end as at 59 to arm 61 of movable cutter blade 35. The lower endlof rod 56 extends downwardly to one side of arms &3 and idand passes through an eyebolt 62 having a threaded shank 63 to receive a Washer 64 and a nut 65 on theiside of arms 43 and M opposite to that of rod 56, see Fig. 8. Turning of'nut 65 in one direction will draw the lower end of rod 56 and the washer e4 toward euchother to effectively clamp armsdf; and 44 therebetween. Rod 56, therefore, is held rigid with respect toarms i and 44. Turning of nut65 in the opposite direction will loosen the clamping relationship above described, whereby rod 56 may be vertically adjusted with respect to eyebolt 62 and the latter and Washer adjusted with respect to arms 43 and 44 after which clamping is again effected by turning of nut 65. Bythe adjustments described above, the tirne of thread cuttingmay be varied and controlled. Rod 3%, lever 42, and the connection including rod 56, eyebolt 62, Washer 64 and nut 65 may be considered primary actuating means, secondary actuating means, and control means respectively, said means .together with link 58 being generally considered as blade actuating means.

In the modifiedform of the invention shown in Fig. .10 several of the parts therein are the same as describedin reference to the preferred form of the invention, and it is deemed only necessary to describe those parts that are difierent. A lever generally indicated at 66, similar in certain respects to lever 42, has a rearwardly extending arcuate portion 67, a curved end portion 625, and aforwardly extending arcuate portion 69. Portions (ST-and 69 are joined to end portion'dfi by arcuate curves 7i and '72. respectively to define an open end sinuous slot 73 to receive rod 39. Portion .67 and 6h areparailel to path 40, whereas portions 71 and '72; are substantially oppositely'curved to path 40 and portionsldi and 69 for a purpose to be described hereinafter.

In the modified form of the invention illustrated in Figs. 11 and 12, the lay L supports a pair of brackets 7 5 to which a stub shaft 75 is secured by set screws 76. block '77 is mounted on shaft 75 intermediate brackets 74 for angular movement thereon and has a rear part that snugly fits between a pair of collars 78 fast on shaft 75 to prevent lateral displacement of block as viewed in Fig. 12. A rod 79, similar in construction to rod 56, has its upper end pivoted as at til to the above described movable cutter blade 35 while a substantial part of the lower end is'slidable in a bore 32, see Fig. ll, in block '77. An upper collar 83 adjustably secured to red '79 coacts with block 77 to move rear end 3 4 of blade 35 downwardly to open or noncutting position when the lay moves forwardly and a lower collar 5.34 also adjustably secured to rod 79 cooperateswithbloclc 77 to move said rear end 34 upwardly to have a cutting operation with stationary blade 27 When the lay is moving reararses-nee water Rod 79, collars s3 and, block 71 and Shaft 75 may be generally considered as blade actuating means lowered whereby motion is transmitted. through rod 56 and link 58 to blade 35 to effect raising of end 35$ for a cutting operation. Cutting of a thread, however, will not occur until the lay is in the latter part of its rearward stroke due to the fact that the cutting edges 37 and 38 of blade 35 and 27 respectively are vertically spaced from each other when the lay is at front center, see Fig. 6Q Cutting Will actually occur at or near back center depending upon where the connection or rod 56 is with respect to arms 43 and 44. T

When the lay is at back center, Fig. 9, end 34 will be at the end of its upward stroke, or in closed position with respect to blade?! and as the lay moves forwardly toward front center rod 39 will contact straight part 52 to effect a reversal of the motion above described. When the lay reaches front center end 34 will be at theend of its down stroke or in open position with respect to blade 7-1 1 In the first modification, see Fig. 10, rod 39 when moving rearwardly from front center will have no eliect on blade 35 during the greater part of its rearward motion. Arcuate portions 67, 69 and the left-hand part of slot 73 are made parallel to path 40 so that end 34 will not move to closed or cutting position untilrod 39 has entered the right-hand part of slot 73 and has contacted arcuate curve 72 whereupon continued rearward motion of rod 39 will depress lever 66 to move end 34 to cutting position at or near back center. During the first part of the forward stroke of the lay, rod 39 will engage arcuate curve 71 and raise lever 66 to return end 34 to open or noncutting position. Continued forward motion'of the rod in-slot 73 will have no eifect on end 34 as was the case when the rod was moving rearwardly inthe slot.

In the second modified form of the invention, Figs. ll and 12, end 34 will be moved in a manner similar to that described in the first modification but will deriveits cut.

ting motion from block 77 when the latter engages collar 84 near back center position to exert a pull on rod 79 as the lay continues to move backwardly. End 34 will be returned to open or noncutting position at front center byengagement of block 77 with collar 83. Rod 79 has a part of its lower end freely slidable in here 8.2 and the relationship between thelatter and said part is such that block 7.7 can find or locate itself angularly with respect to shaft 75 as the lay swings back and forth. However, when block 77 engages collars 33 and 8d, angular movement of the block willstop and a push or pull force will be exerted on red 79 respectively to move end 34 to open and then to closed position. Collars 33 and 84 may be adjusted along rod 79 to vary and control the'time of thread cutting.

t Fig. l3 diagrammatically illustrates the manner in which'cutting of a thread of a stored shuttle is prevented.

After Shuttle S1 or any other shuttle has entered cell 7,

gang G will be raised to the dotted line position, Fig. 1, and remain there for a number of successive picks while cell 8, now in running position, will receive and eject shuttles-for continued weaving. Thread TH, Fig. 13, will extend from shuttle S1 to the selvage of cloth C, and at the start of the storing period will be in the full line position. As the loom continues to Weave the cloth will be moved forwardly by the takeup mechanism (not shown, but well known) and thread TH will be guided over horizontal leg 32 and into notch 33 to assume the dotted line position. That part of the th cad extending from the notch to the shuttle will be rearward of cutting edges 37 tion of the lay.

and 33 and when a cutting operation occurs at or near back center, thread TH will not be cut as would be the case if the latter extended from the point of anchorage (dotted line position) at the selvage directly to the stored shuttle. it is to be understood that the dotted line position of thread TH is only one of many positions it can assume as weaving progresses during storage of a shuttle. When the lay is at front center, part of the thread will be over and under cutting edges 37 and 38 respectively, but the thread will not be cut since, in all forms of the invention, cutting can only occur at or near back center posi- Referring particularly to Fig. 2, the thread or weft OT is'shown in full and dotted line positions which repre sent the positions taken by the thread incident and subsequent to a Weft replenishing operation respectively.

Detection of weft exhaustion followed by a we t replenishing operation and the mechanisms therefor are well known in the art and further elaboration thereof is believed unnecessary. it is deemed sufficient to say that just prior to the insertion of a full bobbin into a shuttle the usual thread cutter will cut the outgoing thread OT at the shuttle eye while the usual pneumatic thread remover 91 is over and adjacent the thread (dotted line position, Fig. 2), to pick up that part of the thread extending from the remover to the shuttle eye. After the transferring operation has been completed, the lay will start rearwardly and the detector and weft replenishing mechanisms will return to their normal position as will the remover which will move from the dotted to the full line position, see Fig. 2. In the present instance the outgoing thread, shown in dotted lines, will extend from the rerno er to the salvage and as weaving continues that portion of the thread adjacent the selvage will be guided over horizontal part 32 and into notch 33 to insure p1acing of the thread between cutting edges and 38 after Whichcutting of the thread will occur at or near back center position of the lay as above described.

After a full bobbin has been inserted into the shuttle the gang will eventually shiftso that cell '7 will be in running position after which shuttle S1 will be picked to the other side of the loom. The new or incoming thread IT will extend from the usual thread holder 92 to the cloth C, and during the beating up of the lay immediately after picking of the replenished shuttle, thread IT will be engaged by a thread pusher 35 to place the thread in the notch of a retaining hook 9 4. The incoming thread will assume the position shownin Fig. 14 having a portion thereof over horizontal part 32 in notch 33 and between cutting edges 37 and 38. Thread IT will be cut in a manner similarto that described for cutting the outgoing thread OT. The thread holder, pusher and hook are Well known and for a further un-.

derstanding of their operation, reference is made to Patpositiomneedless vertical motion of end 3d is prevented,

and a thread cutting operation cannot occur at the wrong time because of loom vibration or the tendency of the weight of the parts depending from pivots 59 or 81 to turn blade 35 counterclockwise, see Figs. 7 and 11.

As stated before, a shuttle may be trapped or misplaced between the reed R and the temple head 21. This comes about when a shuttle enters either shuttle cell 7 or it and rebounds toward the cloth to assume the dotted line position in Fig. 2 because of a strong pick from the opposite side of the loom or malfunction of the usual shuttle holding binder associated with each box. At this time the lay is moving forwardly to cause the shuttle to move the temple head to the dotted line position shown in Fig. 7. Because link 58, in the pre- 'Zt' ferred and first modified forms of the invention, is free to pivot as at 57 and 59, it will also move forwardly thus preventing breakageof the temple, movable blade 35, and any of the parts of the blade actuating means.

In the second modified form of the invention a misplaced shuttle will have the same effect on the temple head as that described for the other two forms of the invention, but in this case collar 83 on rod 79 will have a component of movement downwardly as the lower part of the latter swings rearwardly from pivot 81. This movement urges block 77 counterclockwise about shaft 75 to prevent breakage of the temple, blade 35, and any of the parts of the blade actuating means pertaining to this modified form of the invention.

Although a description of the control of the weft of a stored shuttle and the outgoing and incoming threads.

was made with respect to shuttle S1 only, it is to be understood that the invention is not limited to controlling just these threads but that other threads of other shuttles will be controlled in the same manner when any of them is to be stored or is to have its weft replenished.

From the foregoing it will be seen that the invention sets forth simple means to guard against cutting the thread of a stored shuttle and to guide the outgoing and incoming threads relative to a weft replenishing operation into position to be cut by the temple blades. Also, simple means have been provided whereby the movable blade is always under positive control in all forms of the invention. This positive control is attained by eliminating the use of springs and having positive connections throughout the blade actuating means from the lay to the movable blade. In addition, end 34 is positively held between blade 27 and member 28 frictionally to prevent motion of said end until acted upon by the blade actuating means.

' the first and second forms the first and latter part of the forward motion of the lay respectively resets the blade. By having the cutting operation take place at or near back center, and resetting of the movable blade at or before front center, cutting of the thread of an active shuttle is prevented when the lay approaches front center and the thread lies in the approximate position as that shown for the outgoing thread (full line position) in Fig. 2.

The invention also provides simple control means or connections whereby the latter may be adjusted with respect to levers 4-2 and 66 to vary and control the time of thread cutting, saidmeans including rod 56, eyebolt 62, washer 64, and nut 65 for the preferred and first modified forms of the invention. In the second modified form, collars 83 and 84 are adjustable with respect to rod 79 to vary and control the time of thread cutting.

Although the connections from the movable cutter blade to the lay are positive in nature, the invention in all forms provides simple means to prevent fracture or breakage of the temple, movable blade 35 and the blade actuating means when a shuttle is misplaced. In the first two forms of the invention link 58 is capable of moving forwardly with the temple head if the latter is thus moved because of a misplaced shuttle. In the third form of the invention movement of the temple head forwardly will cause the lower part of rod '79 to swing rearwardly from pivot 81 to effect lowering of collar $3 and attendant angular down motion of block 77 to relieve strain. on the blade actuating means, thereby preventing fracture or breakage thereof.

Having nOW particularly described and ascertained the nature of the invention and in what manner the same is to be performed, it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and that the invention is not limited to the details herein-disclosed, but what is claimed'is:
